Analysis and correction of raw WREN satellite images

Abstract

This paper describes some research related the sensor calibration of an optical remote sensing satellite. The WREN satellite acquires multispectral images, but these raw images need some correction before any application. The columns of the image, which was created by different sensors of the camera, does not contain comparable data, the images have a striped view. The described studies analyze the histograms of the different columns of the images and unified the the distribution for creating a corrected image or calibrate the sensor.
